+# Example Workplan
+
+## Purpose
+
+Establish a focused implementation slice with enough structure for State Hub,
+human review, and follow-on implementation.
+
+## Tasks
+
+```task
+id: MKTT-WP-EXAMPLE-T001
+status: todo
+priority: high
+```
+

+
+## Decision Point
+
+Continue only if diagnostics are clear enough for humans and agents.
